Portland police and Crime Stoppers are offering a $1,000 reward for information leading to an arrest in a hit and run crash that seriously injured a 20-year-old Portland man.

At about 3:30 a.m. New Year’s Day, Conor James McMahon and a friend were waiting for a ride at the corner of North Lombard Street and Jordan Avenue when a man in minivan pulled up and asked if they needed a ride; which they declined.

The driver left, drove about a block away and made a U-turn. The driver sat in the van for a moment, his engine idling.

Police said McMahon stepped out onto North Lombard to see if their ride was coming, when the van’s driver accelerated, running into McMahon, who was seriously injured.

Witnesses said the driver appeared to intentionally strike McMahon, before driving away eastbound on Lombard Street.

The driver was described as a 35- to 40-year-old man with dark, short hair buzzed on the sides and a slight mustache or goatee. The van was a dark-colored Dodge Caravan or similar vehicle that appeared to have a fare meter similar to a taxicab mounted on the dashboard.

Anyone with information on this case can leave a tip on the Crime Stopper’s website; text CRIMES to 274637 and put 823HELP in the subject line; or call 503-823-4357. A Crime Stopper’s app for iPhone and Android phones is also available online.
